FOR ELECTION TO THE BOARD OF DIRECTORS OF QUALITY SYSTEMS, INC.

New York, NY – June 18, 2012 – Ahmed D. Hussein today announced that he has nominated seven highly-qualified director nominees to the Board of Directors (the “Board”) of Quality Systems, Inc., a California corporation (NASDAQ: QSII) (the “Company”) to replace seven directors whose terms expire at the Company’s 2012 Annual Meeting of Shareholders.  Mr. Hussein beneficially owns 9,334,700 shares of common stock of the Company, or 15.7% of the Company’s outstanding shares.  Mr. Hussein delivered formal written notice of his nomination to the Company in accordance with the Company’s amended and restated bylaws on June 15, 2012.

Dr. Hussein stated, “I am confident in the potential of Quality Systems but a hand-picked board is allowing the non-executive chairman to be declared an independent director and act in an inappropriate executive capacity. I believe the chairman’s control is negatively impacting shareholder value. These issues will be further elaborated in my proxy statement.  A board of directors should be truly independent and accountable to all shareholders. I am happy to be able to offer highly qualified director nominees who will bring independence along with substantial strategic, operational, financial and investment experience to the board. Patrick Cline who, with his team, were the architects of the growth of the company, has also joined the slate. These director nominees share my strong enthusiasm about Quality Systems and are willing and able to work with management to achieve the company’s potential.”
